Abstract (en)
An optical information recording apparatus, an optical information recording method, and an optical information recording medium that enable information signals to be recorded precisely by determining recording conditions such as recording power, edge positions of recording pulses, and the like suitably before recording information signals. An edge test signal generation circuit (4) supplies a test signal for optimizing edge positions of recording pulses. In order to suppress the variation in intervals between edges due to mark distortion caused by overwriting, test recording is carried out using this test signal in a plurality of sectors on the optical information recording medium with a test recording start point being shifted at random in each sector by a recording start point shifting circuit (3). A system control circuit (2) calculates an average of intervals between edges in test signals reproduced from the plurality of sectors and determines the difference between the average and an original interval between edges in the test signal, thus determining a compensation volume for edge positions. <IMAGE>
